WHAUR THE GAUDIE RINS

(Refrain)
    Oh, there's meal and there's ale whaur the Gadie Rins
    Wi' the yellow broom and the bonnie whins
    There's meal and there's ale whaur the Gadie Rins
    At the back o' Bannachie.

As I cam' roun' by Bennachie,
A bonnie young lassie there I did see,
A gaed her a wink and she smiled tae me,
At the back o' Bennachie.

    Oh, there's meal ...

Oh I took my lassie on my knee,
Her kilt was shourt abeen her knee,
I says, "My lassie will ye come wi' me,
Tae the back o' Bennachie?"

    Oh, there's meal ...

I says to her, "Pit on your kilt,
Your a gey bra' deem and you're gey weel built,
You can wear your plaidie alang wi' your kilt,
At the back o' Bennachie."

    Oh, there's meal ...

Oh when her mither comes tae ken,
We'll hae tae rin noo fae oor hame,
And sleep in the heather up in the glen,
At the back o' Bennachie.

    Oh, there's meal ...

Oh, here's tae the lassie o' Bennachie,
I'll never gang back for her tae see,
I'll bide wi' my mither until I dee,
At the back o' Bennachie.

    Oh, there's meal ...

(by the way, Alexander, it is "Si Morag" as you wrote, the "St. Morag" I had seen was a typing error)
